Patent JP-H08223688-A (JP)
Title: Speaker
Inventor: TANABE AKIRA
IPC: H04R3/00
Filed: 1995-02-17
Abstract: PURPOSE: To prevent the sound distortion that is caused by an excessive input applied to a speaker and also to prevent the noises caused when a bobbin or a damper hits on other parts. CONSTITUTION: In a magnetic circuit A1, a ring-shaped magnet 22 is placed oppositely against a ring-shaped yoke 21 and the Y and anti-Y sides of the magnet 22 defined around a border line Ox are polarized as the N and S poles respectively. When a coil C1 or C2 is placed opposite to a different magnetic pole over the line Ox due to an excessive input, the damping force is applied to the coil. Thus the excessive movement of the coil is prevented and therefore the sound distortion can be prevented. A damper 15 does not hit on the magnet 22 nor the lower end 19a of a bobbin 19 does not hit on a frame 11 when the damping force is applied to the coil. Thereby, no noise is caused. Furthermore, a deformed junction part 14 is not stretched when the damping force is applied to the coil and therefore no sound distortion is caused by the stretching of the part 14.
